Sled pressure

Generally, sledges are pulled by cows. In the past, Nuzhen, Su Shen, Xibe, Oroqen, Hezhe and other ethnic groups often used dogs, deer, elephants and other animals to pull it. "Geography of Jilin" records: "Before the Qing Dynasty, it was in the northeast of the East China Sea, but it was closely related to the Japanese base, so the dog and deer were separated in the Qing Dynasty." "Feyaka and shrimp in Hokkaido, Japan are a family. Even today, dogs and deer are defined. As a dog, now east of Yilan, livestock train dogs to pull plows. "
